RlVET-SETTING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 643,339, dated February 13, 1900.

Application filed March 21, 1899.

To aZZ whom it may concern:

Be it known that we, JOSEPH W. THOMPSON and LORIN T. FRENCH, residing at Salem, in the county of Oolumbiana and State of Ohio, have invented certain new and useful Improvements in and Relating to Instruments for Setting Rivets, of which the following is a description, referring tothe accompanying drawings, which form a part of this specitication.

The invention is very closely related to that described in the application of Joseph W.

-Thompson, Serial No. 643,641, filed July 6,

1897; and the present description will be confined .more particularly to the features not covered by the claims of that application.

The object of the present invention is to provide a simple, cheap, durable, and convenient instrument by which material of various sorts, particularly that of harnesses and similar articles, may be riveted.

To the accomplishment of this object the invention contributes improvements in punching mechanism, improvements in the riveting or rivet-setting mechanism, and an improved combination of both in one instrument.

The several points of our invention will best be understood by a description of the preferred form of it shown in the accompanying drawings.

In the drawings, Figure 1 is a perspective view of the complete instrument. Fig. 2 is an enlarged detail viewshowing the operation of riveting a loop on one side only. Fig. 3 is a View, partly in section, illustrating the riveting of three thicknesses of leather together. Fig. 3 is a plan of certain details. Fig. at is an end view of Fig. 1. Fig. 5 is a detail view of the punch and its connections with the operating-lever. Figs. 6 and 7 show a modification.

Throughout the drawings like letters of reference indicate like or similar parts.

The frame B is of such shape as to rest upon the base I) and leg I), the latter forminga grip for the hand, cooperating with the hand-lever O, by which the apparatus is operated. The movable carrier or bracket D travels longitudinally upon the frame B by means of the finger-nut F. The screw-threading and other means by which this is accomplished will not Serial No. 09,957. on model.)

be here described, as they are fully set forth in the other application already mentioned. The same is true of the rivet-setting plunger G, spring-holders H for the rivets, and clamp J for the work to be riveted. The clamp J is shown in the drawings integral with the carrier D. Suffice it to say that when the work to be riveted has been placed in front of the plunger the clamp J may be brought against the work to hold it firmly and the plunger adjusted to proper relation withthe work by turning the finger-nut F, and thereby adjusting the carrier D, with all its connected parts, bodily to or from the work.

The features which constitute the present invention are particularly the riveting-bar K, backing or abutting screw L, and punch, with their connections and relations to the other parts. The riveting-bar K is secured at the point 0 and carries, as at M, the riveting head, surface, or point, as the case may equivalent support is to permit a loop or other double form of article to be inserted one part in front of the surface M to receive the rivet and the other part immediately behind it, so asnot to be acted upon by the rivet. In Fig. 2 the tool is shown riveting inside of a loop Vand, in fact, riveting the ends V of the loop in between two thicknesses of leather V", the riveting-bar K lying between the loop V and the leather V. Four rivets WV are shown in place. The backing-screw L, which forms an adjustable part of the abutment Z, is screwed up to a convenient position to allow for the thickness of the portion V of material behind the riveting-bar K. It will also be clear that the adjustable screw L forms, in fact, an ad justable abutment which takes the pressure from the riveting-bar K and enables us to make the bar K of thin and light material. 13 y means of the riveting-bar K it is possible to secure rows of rivets in loops and in loop-fastenings for buckles, which could not be done by forms of rivetinginstruments without such provision.

While the invention is perhaps best suited for use with hollow or tubular rivets, it is of course not limited to such use. Frequently, but particularly when solid rivets are used or tubular rivets which cannot readily perforate the leather, it is desirable to have a punch, and our punch P is so arranged that it may be operated by the same handle 0 as is used for riveting. The punch P is carried on a pivotally-mounted piece Q, secured beneath the lever or handle 0 by a screw or other fastening B. On the end of the pivotallymounted piece Q, remote from the punch P is a stop S, which strikes against the fingernet F when adjusted in the position shown in Fig. 1. In this position the stop S limits the movement of the handle 0, and consequently of the plunger G. When so adjusted, the punch cannot come in contact with the framework or other parts of the instrument. When, however, the adjustable piece Q is turned to the position shown in Fig. 3, the stop S is removed from the finger-nut F, and the punch P in turn is brought to a position to cooperate with the fiat face or table T, adapted to operate as an abutment-surface for the punch in its operation. As the adjustment of the carrier D adjusts the handle O, punch P, and finger-nut F along with it, the proper cooperation of the punch and the table T are in no way interfered with. It is only necessary to turn the nut F until the table T is uppermost. When the adjustable or pivoted piece Q is turned crosswise of the handle or lever O, as indicated in Fig. 5, the punchings can be readily cleaned out from the punch P by means of a pin or small red.

The operation of our invention has already been particularly explained in connection with Fig. 2 and should be readily understood from the drawings and foregoing description. Fig. 3 shows the operation in riveting three thicknesses of leather together where there is no loop or part to go between the riveting-bar K and the adjustable abutment L. In such case the backing-screw or adjustable abutment- L is screwed up against the back of the riveting-bar K to rigidly support it, as shown in Fig. 3.

In the modification shown in Figs. 6 and 7 we show an adjustable riveting-bar K, which has a pivotal movement about the riveting surface or point M. This movement or adjustment is accomplished by securing the bar K at O to the lower end of an arm Y, which is pivoted coaxially to the plunger G byaloose pin Y. This pin, as indicated by the dotted lines, is free to move longitudinally in the abutment Z. No adj ustmentof the abutment is provided, for because of this movement of the pin Y the arm K can be moved to or from the abutment to receive a greater or less thickness of leather or other material behind it, after which the carrier D, with its clamp J, may be advancedto hold the work against the abutment and against the riveting-arm K during the operation of the plunger.

W'e claim,and desire to secure by these Letters Patent, the following:-

1'. In combination in an instrument for riveting, a frame, a plunger, an adjustable carrier D therefor, a lever pivoted in the adjustable carrier D for actuating the plunger, an abutment toward which the said plunger acts, means for adjusting the carrier toward and from the abutment, and an intermediate riveting-bar carrying the riveting head or surface and supported independently of the adjustable carrier, substantially as set forth.

2. A riveting instrument provided with a movable plunger, and a riveting-bar carrying at or near its end a riveting head or surface in alinement with the plunger, and an abutment behind and adjustable relatively to the said riveting head or surface, substantially as set forth. i

3. In combination in an instrument and with the frame or stationary parts thereof, a plunger,an operating-lever, an abutment-,and a riveting-bar, the fulcrum of said lever and the bar being relatively adjustable, said fulcrum and said abutment being also relatively adjustable, and said bar and abutment being relatively adjustable, substantially as set forth.

4. A riveting instrument provided with a frame, a riveting-bar mounted on the frame, an abutment behind the riveting-bar, a plunger, a lever pivotally mounted to operate the plunger, means for adjusting the bar and abutment relatively to each other, and independent means for relatively adjusting the pivot of the lever toward and from the bar, substantially as set forth.

In testimony whereof we have hereunto set our hands this 18th day of April, 1898.
